WebThe ionic radii of trivalent REE ions are about 1 Å, which are compatible to those of Ca 2 +, Na +, Th 4 +, etc., and are significantly larger than those of other trivalent ions such as B 3 +, Al 3 +, and Fe 3 + (Miyawaki and Nakai, 1996). Ionic radii of the trivalent REE ions are systematically reduced from La to Lu with increasing atomic number.
